    FT labs detectors

    Does anybody know how these probes work ?
    They plug in to a audio socket on a phone ,and software drives them.
    So how does this work ?

      radiation hits the sensor creating a pulse, the sotfware counts the pulses per second - that's all.
      it's probably junk in something that small.

      btw, there was a guy who used the cmos camera as a sensor so you only needed the software
      you can probably use these things to know when not to aproach something, but you wont get useable numeric readings from them.

        Hi yes it is the one for radiation I was looking at.
        As I understand the jack plug has 4 poles
        The barrel is the sound in
        The first ring is ground
        The next ring and the tip are the two stereo outputs.
        I am hoping the device powers the device using the stereo connections and uses the audio input for the signal from the detector module.

          probably, by generating a high volume waveform on the audio that can be rectified & smoothed at the device.
          it wont do the amplifier much good though even if it is a clever trick!
